* Default implementation for {@link HapiContext}.
*
* With this class you can configure HAPI and obtain all major HAPI business objects that are
* initialized accordingly. All configuration objects already have reasonable defaults.
* <p>
* When using Spring Framework for initializing objects, you can use the factory methods like this:
*
* <pre>
* <!-- Define the context -->
* <bean id="hapiContext" class="ca.uhn.hl7v2.DefaultHapiContext">
* ...
* </bean>
*
* <!-- Obtain the default PipeParser instance -->
* <bean id="pipeParser" factory-bean="hapiContext" factory-method="getPipeParser"/>
* ...
* </pre>
